The invention relates to improvements in the art of separating Varioussubstances from flowing fluids; Such flowing fluids are known ascarriers and the term carrier is to be understood as meaning any fluidthat' is' directed or kept in motion between given points whetherliquid, gaseous or vaporous and whether hot or cold, or a mixture ofsuch fluids; and, the terms foreigmsubstances l and entrained substancesas used herein are to be understood as meaning any and all Carrierconveyed substances, whether solid or fluid or both, and whether of lessor great er weight than the .Carrier. I

The invention comprises an improved apparatus for utilizin g the forcesof kinetic energy, centrifugal motion and gravity to separate or removeentrained substances from Carrier fluids'.

The invention may be readily understood on reference to the accompanyingdrawings, in which Fig. 1 is a vertical section of a dust Collector,both embodying and illustrating this invention; Fig. 2 is a plan Viewthereof on the line 2-2 of Fig. 1; Fig. 3 is a Vertical sectionillustrating an operation ofthe invention wherein the incoming stream isset into rotation before it'is subjected to the separating Operationwithin the body of the separator; and Fig. 4 is a sectional view on theline l- 4: of Fig. 3. i

Referringto Fig s. 1 and 2, 2 represents the 1nlet pipe through whichthe burdened carrier enters the separator. This pipe and the 'body ofthe separator are coaxial upon a Verr tical axis.' Thebody 3 of theseparator is of considerable depth, usually terminating in a hopper 3'and a drain spout 3". The body 3, 'may be rectangular or circular: ashere shown. The top 4 thereof containsalarge opening 5, from which thecollar 6 rises. This' collar may be cylindrical, butpreferably'ishereinafter explained, The

as the space ll, within the body 3, is called' the accumulation space ofthe separator. The operation of the apparatus shown in lFigs. 1

' and 2 is as follows: v

The direction arrows in Fig. 1 represent the movement of the difierentparts of the Carrier stream outward and downward into.

the separating space A and as indicated the fluid having discharged itsburden of foreign substances and having been completely or largelydeprived of its energy attains practically a static pressure conditionin the central parts of the accumulation space B.. From that positionthe unburdened Carrier fluid may escape from the separator only by wayof the space A andthe annular passage 7; that is, the unburdened'Carrier is forced to find its way out through the incoming stream ofburdened carrier fluid. Thus the final filtration of the fluid isensured, the entering stream serving as the filtering medium therefor:

Flowing downward from the pipe 2 the burdened carrierencounters 'the'conical defiector 9 and is thereby expanded into an um brella-likestream which persists in its move ment until interrupted by the collar6. The centrifugal separation is initiated at that moment and isaccentuated by the immediate effort of the Carrier fluid to turn withinit- A self and. escape upwardly. The gravity separation proceedsnormally at all times. The radial plates 10 successfully defeatinequalities in the stream from the pipe 2 and also defeat the tendencyof the particles to defiect laterally within the space A as contrastedwith the described general downward or longitudinally of the particlestherein. It is to be noted that. the effective cross-sectional loo areaof the separating space A is several times that of the pipe 2 and theopening'7, this being a prerequisite to the persisting downward movementof the burdened carrier Within the collar 6.

The structure of Figs. 3 and 4 eXhibits a tangential or whirl-producingtuyre 11 (having a closed top 11') as a means for promoting a Whirlingcondition in the carrier fluid descending through the pipe 2 The carrierfluid enters the tuyere from the housing 12 and pipe connection 12',supported at a distance above the to of the separating Collar 6 Thelower en of the pipe 2 may be fiared outwardl as shown in Fig. 3 or maybe straight. t closely approach es the suitably supported spreading coneor defiector 9". The action of the separator is as before describedexcept to the extent that it is modified by the initial separation ofthe dust particles within the tuyre 11 and the spiral downward movementthat the tuyere imparts thereto Within the pipe 2 A The initialseparation accomplished by the centrifugal tuyre 11 obviously has theeffect of preliminarily Collecting or massing the dust particles againstthe inner side of the pipe 2, so that they are thrown outward at thelower end of the pipe, and are more certain to be projected against theCollar 6 and to be whirled downward by the carrier stream crossing theseparating chamber A.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The herein described process of separation thatconsists in projecting a burdened carrier stream downward, at one pointdeflecting said stream laterally and thence downward and thence inward,throughout the circumference of the stream, Collecting the separatedforeign substances, and, releasingthe unburdened carrier fluid outwardthrough the first deflected portion of the burdened stream.

2. The separator herein described comprising a separator body having adischar e opening at the bottom for the foreign su stances, incombination with an annular separating chamber erected on the top ofsaid body and in open communication therewith, said chamber being o enat the top and forming the outlet of t e separator, a defiecting conecentrally positioned in said chamber, a burdened carrier inlet pipedescending vertically nearly to said cone and coaxial therewith, and aplurality of laminating plates radially positioned in said separatingchamber, substantially as described.

In testimony whereof I have hereunto set my hand this 26th day of June,A. D. 1926. CHARLES a GILBERT HAWLEY.
